General Description
The HMC344 is a broadband non-reflective GaAs
MESFET SP4T switch chip. Covering DC to 8.0 GHz,
this switch offers high isolation and low insertion
loss and extends the frequency coverage of Hittite’s
SP4T switch product line. This switch also includes
an on board binary decoder circuit which reduces
the required logic control lines to two. The switch
operates using a negative control voltage of 0/-5V,
and requires a fixed bias of -5V. All data is tested with
the chip in a 50 Ohm test fixture connected via 0.025
mm (1 mil) diameter wire bonds of minimal length
0.31 mm (12 mils).
